iNsULA'rnn GLASS-Lilien CANTEEN.

To all 'lc/0m 'it may concern determined temperature for a considerable length of time. I

Another object of the inventlon `1s to pro- -vde an outerjacket and an inner receptacle,

the former having a removable portion which `can be removedvwhen it is desired to remove the inner receptacle for cleaning purposes or for the purpose of replacing a Cit broken receptacle by a new one.

tn the drawings, lforming a portion ot this specication and in which like numerals ofreii'erence indicate similar parts in the several views :Figure 1 is a side view of the canteen. therethrough taken on the' line 2 -2 of Fig. l. Fig. 3 is a section on line 5-5 of Fig. 2.

rthe device comprises an outer jacket 1 which `is formed with a chamber 2. A lglass receptacle 3 of' a configuration con forming substantially with that of' the chamber is located in the chamber, as shown. Theouter receptacle comprises preferably a circular wall @the spaced heads 5 and 6, a substantially cylindrical member 7 anda reuzovable portion 8, thelatter being designed toclose the chamber 2 at one side, as shown 'in Fig. 2. rThe wall 7 is preferably secured to the wall 4 by soldering the walls at 9. The wall 7 is 'constructed to provide a circular concavity 10 in which is soldered an interiorly threaded ring 11. A neck member 12 is soldered or otherwise suitably secured at 13, to the member 7.

The walld is provided .at one side with aflange 16 4which is embraced by the flange i 17 on the head 5, the said flanges being connected with eaeh other by solder.

The neck 12 is4 embraced by an external neck 18,. the-same being secured to the internal neck 12, at 19, and to the wall li, at

20. This neck is formed to provide a horizontal shoulder 21 for a purpose to be here inafter explained; A cover 22 is providedI Fig. 2 is a vertical section for closing the jacket, andas shown, it embodies a circular wall 23 having a base flange 24 and an upper flange 25. The upper tlange is secured to the cap plate 26. Ithe base flange is stamped or pressed to ferm an annular vertical portion 27 to which is secured an. interiorly threaded ring 2S. This ring 1s adaptedto engage an ex- .teriorly threaded ring 29 which is carried by the flange 19 of the external neck-18. Adjacent to the vertical portion 27, the base portion of the Wall 23' is formed to provide a vertical flange 30 which is seated and secured in the recessed portion 31 of the inner member 32 of the closure. i

rlhe inner member 32 of the closure' is spaced from thecap plate 26 and from tre circular wall 23 and the intervening space isoccupied by an insulating material 33 of mineral wool, asbestos, cork, felt, cardboard, or other noob-eat conduct-ing material. The internal neck 12 is spaced from Patented June 2, 1914.

the wall 4:. The 'walls and 7`and 'the heads 5 and 6 are Yspaced from each other and as shown5 such spaces are occupiedby a similar" non-,heat conducting material 3st.

Irllhe detachable portion 8 of the jacket comprises inner and outermembers 35 and 36 whichare' of circular configuration. The inner member is formed with a peripheral horizontald'ange 37 vand withasimilar vertical flange 33,- the latter being secured to the outer member 36,' at .39.'I The peripheral flange 37 ot the inner member has secured thereto an exteriorly threaded ring 4 0 which screws l.into the' ring 11 hereinbefore described. The outer member 36v is preferably provided with an inwardly extending 'dange 4:1 which embraces a similar flange 42 on the wall-it.y The intervening space between the inner and outer members 35 and 36 is iille'd4 with non-heat con-ducting material 43.

The receptacle 3 is provided with a iat bottom portion lll against which a plate 45 is yieldingly pressed .by springs 16 nterf posed between the plate l5 and a similar plate47, the latter being seated upon the wall 7 of the jacket. These springs operate to hold the vessel 3 in a position whereby the 4neck Li8 of the vessel will be extended into the internal neck 12, the portion of the vessel in proximity with the 'lower' end ci the neck being engaged against vthe lower end of the interna-l neck, as shown.- The outer member 36 i'spformed with a central concavity 49, the 'inwardly pressed portion of the member having a central opening therein through which extends a bolt 51. This bolt is provided with a clamping nut 52 which is adapted for clamping engagement against the portion .50 of the member 3G so as t0 hold they bolt against displace ment. The bolt is headed at its outer end at 53, and interposed between the head and the portion 50 in the outer member 36 is a manipulating device 54. This member carries wings 55 which are adapted to be grasped by the hand so that the portion S of the jacket can be readily disconnected from the ring` lll. In order to prevent any possible rotation 'of the ymember 54 I preferably seat the ends of the wings 55 in recesses 5G in the outer member 3G. In addition to the above it is preferable to wipe the threaded portion of the .bolt with solder so as to positively prevent the nut of the bolt from working loose. The diameter of the chamber 2 exceeds the diameter of the vessel 8 so that the latter can be freely moved therein. When it is desired to clean the vessel 3 or sterilize the same the removable portion 8 of the jacket is removed. Pressure is then exerted downwardly on the vessel 3 and by tilting the vessel it may be withdrawnfrom the jacket. To accommodate the tilting movement of the vessel during the actot removing the same from the jacket I preferably provide the internal neck with a down-- wardly and forwardly flared portion 57.

'A' cock plug 58 is designed to close the neck of the vessel 3,- and as shown, this plug A has extended' therethrough the shank 59 of an extracting element. The lower end of this element is headed, -at 60, and conned between the lower face of the plug and the said headed portion .are washers 61 and G2 which operate to prevent withdrawal of the stem 59 from the plug. The top of the plug 4is covered by a metal cap 63. The upper end of. thev stem 59 extends through the cap and it is formed with an eye 64 to which the extracting rings 65 and 66 are pivotally connected.

The bottom of the cover 22 is provided with a shoulder 67. The top 26 of the 'cover is provided with a similar stop 68. The walls 23 of the cover are embracedby a retaining ring 69, the same being mounted on' the coverv so as to permit the latter to be revolved in the ring. This ring is attached to one end ot a chain 70, the latter being suitably supported on the canteen. The Walla of the canteen is provided at'opposite sides with members 71 to which the terminals of a suitable shoulder or belt strap, (not shown), may be attached.

I claim 1. A canteen comprising an insulated jacket having a neck, said jacket having an opening in one of its sides, a vessel removably mounted in the jacket and having a neck extending through and beyond the neck of the jacket, a closure for the neck of the vessel, a closure for the neck of the jacket, and a closure adjustably mounted in the opening at the side of the jacket.

2. A canteen comprising 'an insulated jacket having a neck, said jacket having an opening in one of its sides, a vessel removably mounted in the jacket and having'a neck extending through and beyond the neck of the jacket, a closure for the neck of the vessel, a closure for the neck of the jacket, and al closure adjustably mounted in the opening at the side of the jacket, one of the walls of the neck of the jacket being flared downwardly in the direction of the opening in the side of the neck and being spaced from the neck of the `vessel so as to permit the latter to be tilted, in combination with yieldable means mounted in the jacket and bearing against the vessel so as to hold the neck of the latter normally in the neck 'of the jacket. 3. A canteen comprising an insulated jacket having a neck, said jacket having an opening in one of its sides, "a vessel removably mounted in the jacket and 'having a A neck extending through and beyond the neck of the jacket, a closure for the neck of the vessel, ya closure for the neck of the jacket, and a closure adjustably mounted in the opening at the side of the jacket, the vessel having a flat bottom, and a yieldable plate.

supported by the jacket and bearing against the ilat bottom ofthe vessel and operatin r' to hold the neck of the vessel in the neck o the jacket.

In testimony whereof .I aix my signature in presence of two witnesses.
